Delivering mail to yahoo and google is so hard those days. Almost every server has had this problem even if it is not used to relay spam. Installing DomainKeys can help your server deliver “clean” emails directly to your user’s inbox.

Installation is simple and it’s done on a domain basis. Here is following steps to install DomainKeys on a specific domain.

First check that you are running the latest version on RELEASE or CURRENT of cPanel 11. Run the script

# /usr/local/cpanel/bin/domain_keys_installer username

Where username is the cPanel user.

If you get an error similar to “Domain keys are not installed on this machine.” you either are not running the latest release or current version of cPanel or you have not converted yet to maildir. Maildir conversion is required before you install DomainKeys.

Ok, we just installed DomainKeys for a domain, but how about if we want to install it for all the domains (users)?
Well, here is bash script that will parse all the cpanel users and then run the installation for each of them.
